The two versions are similar but are not compatible and scripts usually only work with one of the other format. You have the option to include or exclude transcript, CDS, and exon annotation from the GFF3 format. This caused featureCounts to not being able to create appropriate counts, as the gene_id was for example missing in that GTF/GFF. Also GFF is able to detect types to group features by genes (genes, transcripts, exons and CDS and the relationship between them by using ID and Parent attributes, see GFF3 Specification for more details ). The following versions of GFF exist: • General Feature Format Version 2, generally deprecated • Generic Feature Format Version 3 GFF2/GTF had a number of deficiencies, notably that it can only represent two-level feature hierarchies and thus cannot handle the three-level hierarchy of gene → transcript → exon.
